I'm still working on it. I think it is ok now : - The random number generator feeds random(4) with entropy via random_harvest(9) - I added hmac software encryptions to be able to use the driver with ipsec(4). Most of the code is stolen from padlock(4), it is not easy to use the same code as OpenBSD : they use some code from crytosoft but in FreeBSD this code is private to the module. And the code of padlock is more "human readable", I think. - I reworked the sessions to use a TAILQ like padlock. - I added few sysctl for debugging purposes. I tested with openssl, and ipsec with all hmac supported by the driver. Seems good, but i'm not able to benchmark ipsec. Sources (7-STABLE): http://user.lamaiziere.net/patrick/glxsb-140608.tar.gz (Yes this is the good version!) If you can test it and provide some review it would be nice. Thanks, regards. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
